After that, lithium aluminum hydride (1.14 g, 30.0 mmol) was added little by little to a solution of 3-methoxymethyloxyphthalic anhydride (3.0 g, 14.4 mmol) in anhydrous tetrahydrofuran (100 ml) under cooling with ice water and the mixture was returned to room temperature followed by stirring for 12 hours. The reaction solution was diluted with ether (300 ml) and a saturated aqueous solution (3 ml) of ammonium chloride was added thereto followed by stirring for 1 hour. The reaction solution was dried over anhydrous magnesium sulfate, filtered off through celite and the filtrate was concentrated to provide 1.71 g (yield 60%) of 3-methoxymethyloxy-1,2-benzenedimethanol as colorless oil.
